Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a voice call method, device, electronic device, and storage medium. Background Art

[0002] Currently, the networking modes of 5G (fifth-generation mobile communication technology) networks are divided into SA (Standalone) and NSA (Non-Standalone). Under the NSA networking mode, 4G (fourth-generation mobile communication technology) and 5G can share the core network, saving network investment. Under the SA networking mode, 5G has an independent core network. Since the SA network has the advantages of high speed and low latency, the SA network has become the mainstream networking mode of 5G networks. In related technologies, operators, taking into account the investment costs, use the same special PLMN (Public Land Mobile Network) to jointly deploy SA networks (Standalone networks) for network deployment in some areas. In the initial stage of network deployment, SA networks do not support VoNR (Voice over NR). Moreover, since SA networks are independent networks and there is no 2G, 3G or 4G network available for voice fallback, calls made under SA networks will be directly dropped, resulting in a low voice call dialing connection rate, which affects the user experience.

[0050] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0051] It is understood that the terms "first", "second", etc. in this disclosure are used to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other and do not indicate a specific order or importance.

[0052] It is further understood that although operations are described in a particular order in the drawings in the embodiments of the present disclosure, this should not be construed as requiring that the operations be performed in the particular order shown or in a serial order, or that all of the operations shown be performed to obtain the desired results. In certain circumstances, multitasking and parallel processing may be advantageous.

[0053] In related technologies, the networking modes of 5G (fifth-generation mobile communication technology) networks are divided into SA and NSA. In the NSA networking mode, 4G and 5G can share the core network to save network investment. In the SA networking mode, 5G no longer shares the core network with the 4G network, but has an independent core network. Compared with the NSA networking mode, the SA network has a higher rate and lower latency. Therefore, the SA network has become the mainstream networking mode of the 5G network. Based on networking cost considerations, operators use the same special PLMN (Public Land Mobile Network) for joint SA network deployment in some areas. In the initial stage of network deployment, the SA network does not support VoNR (Voice over NR, new air interface carrying voice), where NR refers to the network standard of the 5G network and is the global technical standard for 5G communication technology. The applicant discovered that since the SA network does not support VoNR in the initial stage of network deployment, and since the SA network is an independent network, independent of the 4G LTE (Long Term Evolution) network, there is no LTE network (or 2G, 3G network) available for voice fallback. Voice fallback means that when the terminal cannot perform voice services in 5GNR, it falls back to the 4G network through redirection or switching, and VoLTE (Voice over LTE) provides voice services. When the voice call ends, the terminal returns to the 5G network. Therefore, when voice fallback is not possible, making a call in the SA network will result in a direct call drop, resulting in a low voice call dialing connection rate, affecting the user experience. Therefore, in order to solve the above problems, the present disclosure provides a voice call method, which is introduced below.

[0054] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0055] Figure 1 FIG. 1 is a flow chart showing a method for voice communication according to an exemplary embodiment. Figure 1 As shown, the voice call method is used in a terminal and includes the following steps.

[0056] In step S11, in response to the call instruction, the network type of the first network where the terminal resides is determined; the first network is a network of the first network standard for independent networking, and the network type is used to identify whether the first network is a special public network, and the special public network is a public network of the first network standard for independent networking configured with a network of the second network standard.

[0057] For example, in various embodiments of the present disclosure, a terminal may be a UE (User Equipment) that supports 5G networks and 4G networks, such as a mobile phone or other device that can access 5G networks and 4G networks through a SIM card. The first network on which the terminal resides refers to the network provided by the serving cell in which the terminal is currently located. When the terminal resides on this network, it can use the network services provided by this network. The first network standard and the second network standard are different network standards. For example, the first network standard may be a next-generation network standard of the second network standard. For example, in an embodiment of the present disclosure, the first network standard may be NR, and the second network standard may be LTE. When a user dials a call through the terminal, the terminal receives a call instruction generated after the dialing. In response to the call execution, the terminal determines whether the network type of the first network on which the terminal resides is a special public network. The special public network can be understood as a special SA public network of the NR network. The special SA public network refers to an SA public network configured with an LTE network. The LTE network configured with the special SA public network may be an LTE network jointly configured by multiple operators or an LTE network configured solely by a single operator.

[0058] In step S12, a search is performed in the public land mobile network according to the network type, and when a second network of the second network standard is found, a call corresponding to the call instruction is initiated through the second network.

[0059] Exemplarily, if the first network is a special public network, that is, the first network is a public network of the first network standard that is an independent network configured with a network of the second network standard, a further search can be performed in the PLMN to search for a network of the second network standard. When a second network of the second network standard is found, a call corresponding to the call instruction is initiated through the second network. For example, the first network currently located by the terminal is an NR network, and is also an SA network. When the terminal receives the call instruction, it first determines whether the first network is a special SA public network deployed with an LTE network. When the first network is a special SA public network, an LTE network is searched in the PLMN. If an LTE network is found, a VoLTE call is initiated in the LTE network.

[0060] Through the above solution, the terminal can search for a second network of the second network standard in the public land mobile network according to whether the resident network is a special public network, and initiate a call corresponding to the call instruction based on the second network. This can solve the problem of dropped calls when making calls when the terminal's resident network is an independent network, improve the voice call dialing connection rate, and thus enhance the user experience.

[0061] Figure 2is a flow chart showing another voice call method according to an exemplary embodiment. Figure 2 As shown, step S11 includes the following steps:

[0062] In step S111, a special network list is obtained, where the special network list includes network information of at least one special public network.

[0063] Exemplarily, in one implementation, a special network list may be configured locally on the terminal, so the local special network list may be read to obtain the special network list. Alternatively, in another embodiment, the special network list may be configured on the network device side, such as on the base station, and the terminal may request the special network list from the base station corresponding to the first network, or the network device may also be another network element. The special network list includes at least one special public network, for example, a special public network provided by one or more operators in a certain area. The special public network may be understood as a special SA public network of the NR network, and the special SA public network refers to an SA public network configured with an LTE network.

[0064] In step S112, the network type of the first network is determined according to the special network, where the network type includes a special public network or a non-special public network.

[0065] Therefore, by querying the special network list, it is determined whether the first network where the terminal resides is in the special network list. If the first network can be found in the special network list, it is determined that the first network is a special public network. If the first network cannot be found in the special network list, it is determined that the first network is not a special public network.

[0066] Figure 3 is a flow chart showing another voice call method according to an exemplary embodiment. Figure 3 As shown, when the network type is a special public network, step S12 may include the following steps:

[0067] In step S121, when the network type is a special public network, the network of the second network standard is searched in the public land mobile network; the public land mobile network includes: a home public land mobile network (HPLMN) and an equivalent public land mobile network (EPLMN).

[0068] A terminal has only one PLMN. An EPLMN is a PLMN that is on par with the terminal's currently selected PLMN and has the same priority. The EPLMN is primarily used to resolve user residency and roaming strategies between a shared network and the original network.

[0069] This special public network can be understood as a special SA public network of the NR network. The special SA public network refers to an SA public network configured with an LTE network. When it is determined that the first network where the terminal resides is a special SA public network, the LTE network can be searched in the PLMN or EPLMN.

[0070] In step S122, when the second network is found, the call is initiated through the second network using the bearer voice of the second network standard.

[0071] Exemplarily, when an LTE network is searched, since VoLTE calls can be made in the LTE network, the terminal initiates a call based on VoLTE voice.

[0072] Among them, when searching for the LTE network, the terminal can fall back from the 5GNR network to the 4G LTE network through the EPSFullBack (Evolved Packet System) mechanism and initiate a voice call through VoLTE. Among them, EPSFullBack means that when the terminal initiates or receives a voice call in the 5GNR network, it falls back to the 4G network by redirection or switching when 5GNR does not support voice services. VoLTE provides voice services. When the voice call ends, the terminal returns to the 5GNR network.

[0073] For example, since the LTE network configured in the special SA public network can be an LTE network jointly configured by multiple operators or an LTE network configured by a certain operator alone, the LTE network searched can be an LTE network of the same operator (as the operator to which the current terminal user belongs) or an LTE network of a different operator. For example, suppose there are three operators, namely operator 1, operator 2 and operator 3, among which operator 1 configures operator 1's LTE network 1 under SA public network 1, operator 2 configures operator 2's LTE network 2 under SA public network 2, operator 3 configures operator 3's LTE network 3 under SA public network 3, and operators 1-3 configure operators 1-3's common LTE network 4 under SA public network 4. Then, the SA public network 4 is a special SA public network. Assuming that the operator to which the current user of the terminal belongs is operator 1, since LTE network 1 and the current user of the terminal belong to the same operator, LTE network 4 is the LTE network jointly configured by operators 1-3 under SA public network 4. Therefore, when the terminal searches for LTE network 1 or LTE network 4, it can execute EPSFullBack to fall back to LTE network 1 or LTE network 4, and initiate a VoLTE voice call through LTE network 1 or LTE network 4.

[0074] Figure 4 is a flow chart showing another voice call method according to an exemplary embodiment. Figure 4 As shown, when the network type is a non-special public network, step S12 includes the following steps:

[0075] In step S123, when the network type is a non-special public network, the call is initiated through the first network using the bearer voice of the first network standard.

[0076] Exemplarily, the special public network can be understood as a special SA public network of the NR network. The special SA public network refers to an SA public network configured with an LTE network. If the first network where the terminal resides is identified as a non-special SA public network, the terminal can respond to the call instruction and initiate a VoNR voice-based call based on the 5GNR network first.

[0077] In step S124, when the call initiated by the high-definition voice of the first network standard fails, the mobile country code of the user identification card is obtained.

[0078] Figure 5 FIG. 1 is a flow chart showing another method for voice communication according to an exemplary embodiment. Figure 5 As shown, step S124 includes the following steps:

[0079] In step S1241, when the call initiated by the bearer voice of the first network standard fails, an evolved packet system fallback is performed.

[0080] In step S1242, when the evolved packet system falls back to the third network of the second network standard, the call is re-initiated through the third network using the bearer voice of the second network standard.

[0081] In step S1243, when the EPS fallback fails, the mobile country code is obtained.

[0082] Taking the first network standard as NR and the second network standard as LTE as an example, if the terminal fails to initiate the call with VoNR voice in the NR network, it executes EPSFullBack. If the EPSFullBack is successful and falls back to an LTE network, it initiates a call based on VoLTE voice in the LTE network. If EPSFullBack is successful, the MCC (Mobile Country Code) of the user identification card is obtained. The user identification card can be a SIM (Subscriber Identity Module) card, a USIM (Universal Subscriber Identity Module) card, a UIM (User Identity Model) card, etc. Among them, the resources of the mobile country code are uniformly allocated and managed by the International Telecommunication Union (ITU) and are used to uniquely identify the country to which the mobile user belongs.

[0083] In step S125, the network of the second network standard is searched in the public land mobile network according to the mobile country code; the public land mobile network includes: a home public land mobile network and a peer public land mobile network.

[0084] Exemplarily, each user identification card is configured with an MCC code for indicating the country to which the user identification card belongs. Step S125 may include: determining whether the HPLMN or EPLMN corresponding to the terminal is the same, and searching for the network of the second network standard in the HPLMN or EPLMN if the countries are the same.

[0085] For example, in one embodiment, taking the first network as an NR network as an example, after obtaining the MCC of the user identification card of the terminal, the PLMN code corresponding to the HPLMN or EPLMN is obtained. If the PLMN code includes the MCC code of the user identification card, it can be determined that the country to which the HPLMN or EPLMN belongs is the same as the country indicated by the MCC code in the user identification card, and the LTE network is searched under the HPLMN and EPLMN.

[0086] In step S126, when the second network is found, the call is reinitiated via the second network using the bearer voice of the second network standard.

[0087] For example, taking the second network as an LTE network, when the terminal searches for an LTE network, the terminal can fall back to the LTE network and initiate a VoLTE voice-based call in the LTE network.

[0088] Figure 6 FIG. 1 is a flow chart showing another method for voice communication according to an exemplary embodiment. Figure 6 As shown, the method further includes the following steps:

[0089] In step S13, in the case where the terminal resides in the first network, dialing information is received.

[0090] In step S14, the call command is generated according to the dialing information.

[0091] Exemplarily, the first network may be an NR network. When the terminal receives dialing information generated by the user dialing in the NR network where it resides, it triggers a call instruction according to the dialing information.

[0092] Figure 7 FIG. 7 is a block diagram of a voice communication device 700 according to an exemplary embodiment. Figure 7 The device includes a network type determination module 710 and a call instruction execution module 720.

[0093] The network type determination module 710 is configured to determine the network type of the first network on which the terminal resides in response to a call instruction; the first network is a network of the first network standard for independent networking, and the network type is used to identify whether the first network is a special public network, which is a public network of the first network standard for independent networking configured with a network of the second network standard.

[0094] The call module 720 is configured to search the public land mobile network according to the network type, and when a second network of the second network standard is found, initiate the call corresponding to the call instruction through the second network.

[0095] The network type determination module 710 includes: an acquisition submodule and a determination submodule.

[0101] Optionally, the call module 720 includes: a second call submodule, an information acquisition submodule, a second network search submodule, and a third call submodule.

[0102] The second call submodule is configured to initiate the call through the first network using the bearer voice of the first network standard when the network type is a non-special public network.

[0103] The information acquisition submodule is configured to acquire the mobile country code of the user identification card when the call fails to be initiated using the high-definition voice of the first network standard.

[0104] The second network search submodule is configured to search the public land mobile network for a network of the second network standard according to the mobile country code; the public land mobile network includes: a home public land mobile network and a peer public land mobile network.

[0105] The third call submodule is configured to re-initiate the call through the second network using the bearer voice of the second network standard when the second network is found.

[0106] Optionally, the information acquisition submodule is configured to:

[0107] If the call fails to be initiated by the bearer voice of the first network standard, performing an evolved packet system fallback;

[0108] In a case where the evolved packet system falls back to a third network of the second network standard, re-initiating the call via the third network using a bearer voice of the second network standard;

[0109] In case that the evolved packet system fallback fails, the mobile country code is obtained.

[0110] Optionally, the acquisition submodule is configured to:

[0111] Obtain the special network list stored locally on the terminal; or,

[0112] Get the special network list from the network device.

[0113] Optionally, the voice communication device further includes: a dialing module and a generating module.

[0117] Through the above solution, the terminal can search for a second network of the second network standard in the public land mobile network according to whether the resident network is a special public network, and initiate a call corresponding to the call instruction based on the second network. This can solve the problem of dropped calls when making calls when the terminal's resident network is an independent network, improve the voice call dialing connection rate, and thus enhance the user experience.
